I bought a used one from Epps a few months ago and love it. It's a Navy Arms import originally made by Uberti. Uberti still has them listed on their site, so my guess is that the EMF is an Uberti as well.
Mine is very trim and well-finished. A real joy to handle, and the rolling block mechanism is just plain simple and nice.
The only drawback is that the trigger is downright heavy. No creep, but at 8lbs the rifle tends to want to pull as you fire. Researching original rolling blocks came up with a solution: make a new trigger spring. I removed my trigger spring and re-measured the pull at 3.5lbs, which comes from the main spring. I made a new trigger spring out of music wire and now have the trigger down to 4.5lbs. It's *much* better, but I still want to take it down lower and maybe have a smith polish the sear... ideally, I'd like to keep it at 3.5lbs, but with the trigger spring in place.
I can't speak with authority about the accuracy because I've only taken mine plinking. My research didn't turn up any conclusive evidence one way or the other, but did show that headspace is critical (as is with all rolling blocks), so that could vary from rifle-to-rifle.
I've also read about people rechambering to 357 Maximum, which would be a killer combination of small, but powerful. I'd definitely want an experience gunsmith to OK it, though, as this truly is a baby rolling block and, generally speaking, they aren't the strongest actions out there.
Anyways, I'm not sure I'd spend $750 on a new one, but I paid considerably less than that for my used, but excellent one, and I'm very satisfied.
